Not sure that I get it right.
Something like that:
```` C++
std::string  GetSourceCharset(void)          const
{ return     m_sourceCharset;          }
std::string  GetTargetCharset(void)          const
{ return     m_targetCharset;          }
unsigned int GetTargetSingleCharMaxLen(void) const
{ return     m_targetSingleCharMaxLen; }
````
